Unbeknownst to the mice they are the products of a ten-year secret genetic engineering research programme, which is about to conclude. The mice, fed up with their incarceration have been plotting their escape for some time. But when one of them overhears the goons (lab technicians) talking about the Vivi Section they decide there is no time to waste. They must put their escape plan into effect immediately…..

The mice were filmed by experienced wildlife cinematographer Marianne Wilding who has worked extensively on wildlife programmes for broadcasters throughout the world - she was one of the first westerners to film Panda's in their natural habitat and she was also responsible for the footage used in the old Carling Black Label Squirrel "Mission Impossible" advert!

Marianne found filming animals for a drama an interesting challenge. "Mice don't take direction, can't learn lines and unless you've got a stash of cheddar they aren't interested. There were a few artistic differences, a bit of tension on set but you expect that sort of thing with so many large egos in one cage".
